Wishing to meet with President Obama’s White House energy and environment adviser Carol Browner, Sen. John Barrasso (R-Wyo.) has delayed the nomination of Lisa Jackson to be Obama’s Environmental Protection Agency administrator. He placed an anonymous objection to the unanimous consent resolution to move the nomination without a roll call vote on Tuesday, and raised his concerns with Sen. Barbara Boxer (D-Cal.), chair of the Senate Committee on Environment and Public Works, on Wednesday.

The bottom line is Senator Barrasso is concerned about this new structure with an appointed energy czar in the White House with no accountability in the White House. Just about how that will operate. He wants to know that. He wants to ensure sufficient transparency and oversight. He wants to be convinced Congress will have the ability to get answers from the appointed czar, Carol Browner. At this stage, he’s not convinced that’s the case.

Yesterday, Browner participated in President Obama’s economic briefing, with National Economic Director Lawrence Summers, Office of Management and Budget Director Peter Orszag and White House Policy Council Director Melody Barnes.

Granta Nakayama, a Bush administration appointee, is the interim EPA administrator. According to E&E News, Nakayama “has been a noncontroversial figure since joining EPA as its top enforcement official in July 2005.”

Shapiro, 60, has previously been a senior official in the Office of Water, director of EPA’s Office of Solid Waste, and deputy assistant administrator in EPA’s Office of Air and Radiation, where he helped implement the 1990 Clean Air Act amendments. He also has held positions in EPA’s Office of Prevention, Pesticides and Toxic Substances.
